COOKING-STOVE. I

Specification of Letters Paar No. 8,047. dated April 15, 1851.

To all whom it may concern: h

Be it known that I, DENNIs G. LITTLE-. FIELD, of Lowell, in the countyof Middlesex and State of Massachusetts, have invented a new and usefulImprovement in Stoves, by which They May be Adapted to the Combustion ofEither Wood or Coal, as May be Desirable; and I do hereby declare thatthe same is described and represented in the.

following specification and accompanying drawings, letters, figures, andreferences thereof.

Of the said drawing Figure 1 denotes a front elevation of a stoveconstructed with myv improvement, the fire place door being representedas thrown open. Fig. 2 is a transverse, central and vertical section ofit. Fig. 3 is a vertical and central section taken in a plane supposedto be at right angles to the plane of section of Fi 2.. Fig. 4 is a sideelevation of the coal ender as removed from the fire chamber.

In the said drawings A represents the fire chamber, or place where thefuel is placed and putin combustion. It is provided with a circular orother proper shaped stationary or turning grate B, which is arranged inthe floor of the chamber and directly over an ash chamber C. An oven orair heating chamber D is disposed directly over the chamber ofcombustion A, and is surrounded on its sides by a consecutive flue spaceE. On each side of the ash pit C, there is a lateral chamber F, whichcommunicates with the cha-mberA, by means of a descending flue G whichleadsfrom or near the top of the chamber A, downward into the rear partof the said chamber F. Out of the opposite or front part of each of thechambers F, a vertical flue H, leads and enters or opens into the lowerpart of the flue space E,

which partly surrounds theoven.

The discharge flue of the fire place is seen at I, and as placed at theback thereof and between the two descending flues G, G. The flue spacesurrounding the oven opens into the said discharge flue, the fire placebeing made to open into it likewise, and to have a closing damper orslide by which the communication may be cut off except through 1 thedescending flues, lateral chamber, as

cending flues, and flue space around the oven, as described. I

The chamber over the fire place may be made and used as an oven for.baking or it may be conducted and employed as an air heating chamber,the air as. heated in the same being suffered to escape therefromthrough suitable openings or conductors made in the top or other. properpart of the said chamber. I I I The fire chamber shouldbe of a sizesuflicient to receive sticks of wood of the ordinary size, say about twoor tl1ree-,feet in length, while the door way or opening a should bemade of a width greater than that of the coal fender or basket K, whichis a circular or other proper shaped hoop or fence, made separate fromthe fire grate, and to rest upon thefloor of the fire chamber and tosurround the grate. This fender or hoop fence is for the purpose ofholding mineral coal, when such is used for fuel instead of wood. henwood is used, such fender is to be removed from the fire place, the doorway of such being made large enough to allow of either the removal orthe insertion of the fender as require.

In order that the basket may be easily supplied with coal, and still bemade to hold a large quantity I construct'it higher in rear than it isin front as seen in Figs. 2 and 4. The bed or mass of coal lyingjinitwhen it is so made generally permits a sloped surface on its top againstwhich the coal while being supplied from a hod are usually throwninstead of being thrown directly against the back part of the fender.And thus by such a construction of the fender, its back part is more orless preserved from injury by means of coals being thrown against it,when itis in a red hot or very heated state.

My improvement and what I claim Consists in the peculiar arrangement ormanner of combining the fire place, the descending or diving flues, theash pit, the lateral chambers, the ascending flues, the centraldischarge flue, the oven or air heating chamber and its surrounding fluespace,

all as represented in the drawings, and as,

hereinbefore specified.

In testimony whereof I have hereto set my signature this third day ofDecember A. D. 1850. I I DENNIS G. LITTLEFIELD. Witnesses:

A. R. BoYN'roN, A. T. JoHNsoN.
